OYSTER-SHUCKING OR OYSTER-OPENING KNIFE.

SPECIFICATION formingpart of Letters Patent No. 715,988, dated December 1 6, 1902.

Application filed February 11, 1901. Serial No. 46,947. (No model.)

To all whom it may concern/.-

Be it known that we, ROBERT H. OooLEY and HARRY WV. BISHOP, citizens of the United.

States, residing in Baltimorecity, in the State of Maryland, have invented a new and useful Oyster-Shucking or Oyster-Opening Knife, of which the following is a specification.

' Ourinvention relates to an implement more especially designed for opening oysters or other shell-fish easily and quickly and in a cleanly manner; and the invention has for its object to provide a simple, inexpensive, efficient, and durable tool of this character.

The invention consists in certain novel features of construction and combinations of parts of the implement, all as hereinafter described and claimed.

Reference is to be had to the drawings heretofore filed and which are prayed to be taken as a part hereof, in which the letters of reference indicate the same parts in all the views.

Figure 1 shows a side View of the whole knife. Fig. 2 shows a top View of it. Fig. 3 shows an end view of the lever C. Fig. 4

shows a top view of the end of the opener, with the bolt P out and the lever O detached and indicating the place F in which thebolt P will fit. Fig. 5 shows a side view of one end of the opener, indicating by the use of dotted lines the places where blade B and bolt P will be attached. of a modified form of the blade B, having the slot A therein. Fig. 7 shows the bolt P and the nut X detached.

This implement is made of cast or wrought iron, with two levers H and C, pivoted together near one end, and the blade or knife B, held to the short arm of the lever H and projecting forward from the end of the short arm of said lever. The lever H is formed as a suitable handle or stock, whichis made hollow to lighten it, and may be securely and comfortably grasped by the hand of the operator and is provided with a slot through which the handle portion of the lever 0 passes and is fitted therein loosely by a pivot. Both levers are pivoted together, and forward of this pivot their short arms, together with groove S in the end of the lever O and the bolt P, form pincer-like jaws, which are adapted to be Fig. 6shows a View steel bolt, with a sharp point of four sides to pass above the surface of the lever H, as indicated in Fig. 5, and is to be made tight and held in place by the nut X, as indicated in said figure. This bolt is to be made with a shoulder and to pass through the lever H in the place F, as indicated in Fig. 4:. It is to have a thread on the end passing through said lever H under the shoulder, to which can be screwed the nut X.

The lever O is to have a bend in the short arm, as indicated by drawings, and at the end is to have the claw or groove S cut therein, as-indicated in Fig. 3. The groove S by reason of the bend in the lever C When operated will come down upon the point of bolt P, said point fitting into groove S, S and P when brought together in the manner set forth forming a dovetailed jaw or breaker which is to break the end of the shell of the oyster or other shell-fish, into which opening the blade B can be easily inserted. Under the long end or handle of lever H is to be attached by a screw a curved spring that will move over the top of the long end of the lever O, which will force the jaws open when released by the operator.

We are aware that other inventions have been patented of this character, and all we claim is- The combination in an oyster-opening implement of two pivoted levers forming a handle and pincer-like jaws, and a knife or blade held detachably to one jaw, which has a bolt with a sharp point near the end of one of the levers, and a groove in the end of the other lever substantially as set forth.
